>WHAT I MEANT BY OVERPRODUCE IS DO THEY HAVE TO MANY BABIES? BECAUSE
>MOST ANIMALS HAVE MANY OFFSPRINGS FOR A BETTER CHANCE OF SURVIVAL

Many placental mammals have only one offspring at a time. This
includes all whales and dolphins, elephants, cattle, and others.
Felines and canines have "litters" of several offspring.

Many of the 'higher' mammals which have only one at a time invest a
great amount (years worth) of parental attention into the offspring
to increase the chances of survival, rather than leaving the progeny
to their inate instincts after only a few weeks. This would include
toothed whales, elephants, and humans.

The issue then becomes having an offspring too often rather than too
many at one time.
